Abstract: A light emitting keyswitch includes a board, a cap, a lifting mechanism disposed between the board and the cap, a membrane switch including first and second substrates, an LED, and a transparent hollow elastic body. The first substrate has a first outer surface and a first inner surface. The second substrate has a second outer surface and a second inner surface. A switch circuit is disposed between the first and second inner surfaces. A copper circuit is formed on the second inner surface. A hole is formed on the first substrate. The LED is disposed on the second substrate, passes through the hole and is coupled to the copper circuit. The transparent hollow elastic body is attached to the first outer surface for covering the LED and the hole and is located under the cap. When the cap is pressed, the lifting mechanism or the cap triggers the switch circuit.

Abstract: A keyswitch includes a cap, a support structure, a first magnet, and a baseplate having a bending arm protruding from the baseplate and a support rib extending horizontally to form a receiving space with the bending arm. The support structure includes a first support member pivoted to the baseplate and against the cap and a magnetic permeable plate extending from the first support member and being above the receiving space. The first magnet is inserted into the receiving space to be supported by the support rib and be pressed by the bending arm. When the cap is pressed to make the magnetic permeable plate away from the first magnet as the first support member rotates, the cap moves to a pressed position. When the cap is released, a magnetic attraction force between the magnetic permeable plate and the first magnet drives the magnetic permeable plate to approach the first magnet.

Abstract: A key structure is provided. The key structure includes a base plate, a key cap and a lifting mechanism is provided. The base plate includes a first bottom wall. The key cap is disposed opposite to the base plate and includes a first cap wall. The lifting mechanism is movably connected between the key cap and the base plate, so that the key cap could reciprocate with respect to the base plate. The lifting mechanism includes a first lower shaft portion and a first upper shaft portion, which are respectively movably connected on the same side of the key cap and the base plate. When the key cap is in a released state, the first upper shaft portion presses against the first cap wall, but the first lower shaft portion is separated from the bottom wall by a maintaining gap.

Abstract: A keyswitch includes a bottom board, a cap structure, a lifting mechanism, and an elastic member. The lifting mechanism is detachably connected to the cap structure and the bottom board to make the cap structure movable upward and downward relative to the bottom board. The elastic member is connected to the cap structure so as to be detached from the lifting mechanism together with the cap structure when the cap structure is separate from the lifting mechanism.

Abstract: A key switch includes a base, a key cap, a supporting mechanism, a link bar and a buffer member. The key cap is disposed above the base. The supporting mechanism is connected to the key cap and the base to allow the key cap to move relative to the base upwardly and downwardly. The link bar includes a lower linking end. The buffer member and the base are two independent components. The buffer member is disposed on the base and made of material softer than material of the base. A restraining structure is formed on the buffer member. The lower linking end movably passes through the restraining structure. When the key cap moves relative to the base upwardly and downwardly, the lower linking end is driven to move within the restraining structure correspondingly, so as to reduce noise during movement of the lower linking end relative to the base.

Abstract: A keyswitch structure includes a base, a keycap, a first support, a second support, and a connection structure. The keycap moves up and down relative to the base through the first support and the second support. The connection structure is disposed on the base and includes a vertical-motion limiting part and a horizontal-motion limiting part. The first support includes a rod-shaped connection portion and is connected to the connection structure through the rod-shaped connection portion. The vertical-motion limiting part prevents the rod-shaped connection portion from vertically moving. The horizontal-motion limiting part limits the horizontal movement of the rod-shaped connection portion. The vertical-motion limiting part and the horizontal-motion limiting part are separated in the rotation axis of the rod-shaped connection portion.
